I the I/O on the dspMC is fine for most operations, as far as human interface devices, with a control head type CNC control, it would make wiring easier to have the PPort running the MPG, buttons on the control panel etc. Othewise we're running wires all the way back to the cabinet, which is fine for a 1 off, but we're currently looking at making a couple tables etc so if we did build more it would be advantageous to be able to hook up to the control right at the control head vs going all the way back to the cabinet for everything. Would probably be a good feature for the dsp to have.
